GN Drilling Mud Decanter Centrifuge and Centrifugal Pumps for Offshore Drilling Company

Recently GN drilling mud decanter centrifuge and centrifugal pumps are shipping to offshore drilling company.


The drilling mud decanter centrifuge is equipped with offshore lifting skid, compared with the onshore drilling mud decanter centrifuge, the skid for offshore drilling is special designed for safety and convenient lifting for offshore purpose, but without DNV 2.7-1 lifting certificate. When DNV 2.7-1 lifting certificate for the lifting pad is required, the skid should be designed specially. The stainless steel cabinet positive pressurized VFD control panel is separately on the ground, with main motor, back drive motor and pump motor 3 VFD, which is from ABB, YASKAWA, etc. famous brand, the other like PLC and touch screen and other electrical conponents from Siemens and other famous brands. The decanter centrifuge bowl and the screw core shaft are made of duplex stainless steel SS2304 by centrifugal casting, which is superior to the performance of SS304 and SS316.The solids outlet and fluids distribution port is protected by replaceable hard alloy sleeve. The wear resistant and anti-skid bars welded inside the bowl can effectively reduce the wear of the bowl under operation. The screw main material is also duplex stainless steel 2304. The screw blade is protected by tungsten carbide tiles, which is replaceable hard alloy plate.
The centrifugal pump all the parts are interchangeable with international brand pump, so the client can source the parts easily. The pump casing made from hard ductile iron alloy, which increased abrasion resistant performance. The pump skid is special designed for client’s particular requirement.


Except for drilling mud decanter centrifuge and centrifugal pump, we also produce linear motion shale shaker, mud cleaner, desander, desilter, vacuum degasser, mud agitator, mud tank system, etc. solids control equipments for the onshore and offshore drilling. For more information, pls contact with GN solids control.

Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.


3. 4 units of GNJBQ055G mud agitators installed on the mud tank for agitating of drilling mud
4. 1 unit of GNSB3X2C-9J centrifugal pump
5. 1 unit of GNSLH-110C jet mud mixer with mud mixing hopper and 11KW mixing pump installed on the skid
6. 1 unit of GNZYQ1000A mud gas separator
7. ATEX electric control system for the whole system


8. Trip tank with pipelines and accessories
9. Shaker tank with pipelines and accessories
10. Mixing tank with pipelines and accessories

Drilling Mud Centrifugal Pump and Mud Agitator for Africa Client

Recently one batch of drilling mud centrifugal pump and mud agitators are ready to ship to Africa client.
The drilling mud centrifugal pump can be used as drilling mud transfer pump, mud pump charging pump, trip pump, desander desilter feeding pump, water pump, mixing pump, etc., we produced different model drilling mud centrifugal pump for different flow rate and lifting head.


The mud agitator consists of heavy duty gearbox and explosion proof motor, which is connected directly, it will be installed on top of mud tank for drilling mud agitating, to prevent the solids deposition in the drilling fluids circulation system, to ensure stable performance and uniform mixing of drilling fluids.
Features of GN G version mud agitator:
1. The helical bevel type heavy duty gearbox runs smoothly with less noise.
2. The motor is directly connected to the input shaft of the gearbox without belt transmission, the speed of the mixing impeller is constant.
3. Compact foorprint and reliable operation.
4. High mixing strength and wide agitating range, avoiding the phenomenon of current overload when the motor starts.
5. Including agitator shaft, double or single layer impeller, stabilizer
6. Except for direct connected G version mud agiator, GN also produce coupler type E version mud agitator, vertical type mud agitator.
The selection of motor power and impeller is usually determined based on the following points:


a. Mud tank type – cylinder or rectangle
b. Mud Tank size
c. Mud specific gravity
d. Rotation speed ratio
After collecting relevant information, we will select the mud agitator proper model and confirm motor power, shaft length, and impeller.
If you need more solids control equipments for mud tank system, such as mud mixing hopper, mud gun, submersible slurry pump, screw pump, shale shaker, mud cleaner, decanter centrifuge, vacuum degasser, pls contact with GN solids sales engineer.
